The Index of Productive Syntax (IPSyn; Scarborough, 1990) is widely used to measure syntax production in young children. The goal of this article is to promote greater clarity and consistency in machine and hand scoring by presenting a revised version of the IPSyn (IPSyn-R) and comparing it with the original IPSyn (IPSyn-O).
Longitudinal syntax production in 10 30- and 42-month-old typically developing children drawn from the Child Language Data Exchange System (MacWhinney, 2000) Weismer corpus was examined, using both the IPSyn-O and the IPSyn-R.
The IPSyn-R provided nearly identical scores to the IPSyn-O with the exception of scores affected primarily by 1 modified noun phrase structure. Structures ranked as more advanced were produced less frequently. The results also reveal which of the IPSyn-R's 59 structures were most and least likely to be produced by this sample at these ages.
The qualitative and quantitative differences between the IPSyn-O and the IPSyn-R are relatively minor. The IPSyn-R can make it easier to score the IPSyn, both by clinicians and researchers, and facilitate the IPSyn's move to machine scoring of language samples.
产出性句法指数（IPSyn；斯卡伯勒，1990）被广泛用于测量幼儿的句法产出。本文的目的是通过呈现IPSyn的修订版（IPSyn-R）并将其与原始的IPSyn（IPSyn-O）进行比较，以促进机器评分和人工评分的更高清晰度和一致性。
使用IPSyn-O和IPSyn-R，对从儿童语言数据交换系统（麦克温尼，2000）韦斯默语料库中抽取的10名30个月和42个月大的典型发育儿童的纵向句法产出进行了研究。
IPSyn-R给出的分数与IPSyn-O几乎相同，只有主要受1种修改后的名词短语结构影响的分数除外。被列为更高级的结构产出频率较低。结果还揭示了IPSyn-R的59种结构中，在这些年龄该样本最有可能和最不可能产出的结构。
IPSyn-O和IPSyn-R之间的定性和定量差异相对较小。IPSyn-R可以使临床医生和研究人员更容易对IPSyn进行评分，并促进IPSyn向语言样本的机器评分发展。
